Fazal Ahamed Kader Sulthan, 32, had dropped his wallet in the taxi driven by Samart Promchart, 28, on Sunday night.
Samart found the wallet the following morning containing US$1,500 and Bt7,000 and took it to radio station FM91 Sor Wor Phor, whose listeners located Sulthyan.
The station arranged for driver and passenger to meet at 11am on Thursday.
Sulthan gave Samart Bt1,200 as a reward. The radio station gave the cab driver a “good man” T-shirt.
Samart said he’d picked up Sulthan and his family at Mahanakhon intersection at 9pm Sunday and drove them to Soi Sathupradit 19.
